Well, I got the opportunity to see snow today! I think its the first time I saw snow in about 15 years!....I brought a big box of it home for my daughters.
Oh, I saw the snow from this freak snow storm that was moving across central Alabama as I was on my way to meet up with nautiquelfe.
The boat is in awesome condition and he got a great deal on it. Because we live so close to each other, he asked if he could bring it down for me to have a look. Well, I thought it might be better for me to travel to his house to check it out.
The port engine runs and both have fire, so when the starboard engine is repaired, he'll have a great boat for a great deal!....
The Starboard motor, PTO cylinder had some signs of detonation. But, the battering of the piston and head could actually be from a piece of the RAVE valve that appears to have hit the piston or ring, breaking a piece off. The RAVE slide valve appears to be the wrong one. I'll look at that shortly.
You guys would not believe what kind of condition this motor is in. I totally expected to run into the aluminum oxide problems on the bolts and have a hard time removing the simple things like the carbs. Well, I was able to pop the exhaust manifold, carbs, PTO head and a couple other things without running into the first seized bolt. Either this boat spent more time on land or when it was in the water, it was in snow melt lakes!......
I believe nautiquelfe is going to decide on a new engine rather than just do an upper end. Because it's a 98 model, I tend to agree with his idea......"why not spend the extra couple bucks to get the entire engine with a guarantee".....? I guess that makes sense. When you only take the engine down, inspect and replace the broken part, you have no guarantee that something else will not break. Like he said, "I don't want to be nickel and dime to death"....so, good point.
Check out the snow!.........
Yeah, the RAVE valves in his motor are from the RFI models. Our slide valves for the carbed 787 through these years is #29054358 and the one he has in his 787 is #2904354.
I'm attaching a couple pix I took with my cell camera. They aren't the greatest in clarity, but it may give an idea. The head over the piston that was beat up, is really bad around the outer edges, where the head is closest to the piston. So, I think the pebble look is from the piece of RAVE and chipped piece of ring done the damage.
What I found strange was the water jacket side of the head. If you look close, you'll notice a piece of the aluminum casting where it seals the water flow direction is cracked all the way down. I've never seen this. Although the engines appear brand new, it seems that this starboard engine may have been taken apart before. The wrong slide valve and the broken water jacket piece. I'm wondering if it was done with screwdriver in prying or maybe, something heavy dropped on it while they (whoever) had the engine apart before.
